Abstract
Abstract A homogeneous liquid nonionic based antimicrobial conditioning shampoo which includes about 0.5 to 2.5% of the antimicrobial agent, 1-imidazolyl-1-(4-chlorophenoxy)-3,3-dimethylbutan-2-one, solubilized in an aqueous solution of critical amounts of a four component mixture of the following specific non-ionic ingredients: a. about 2-20% by weight of a polyoxyethylene hexitan mono-higher fatty acid ester, b. about 4-10% by weight of a tertiary amine oxide, c. about 1-7% by weight of a fatty acid mono- or di-ethanolamide, d. about 0.05-1.0% by weight of a polyacrylamide having a molecular weight of 100,000 to 3,000,000. This shampoo is transparent in appearance and should preferably contain 65-80% water.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
111 words
A homogeneous, liquid, nonionic based, antimicrobial, conditioning shampoo containing about 0.5-2.5% of 1-imidazolyl-1-(4-chlorophenoxy)-3,3-dimethyl butan-2-one solubilized in an aqueous vehicle, wherein the aqueous vehicle constitutes about 65-80% by weight of water containing four nonionic components comprising about 2-20% by weight of a polyoxyethylene hexitan mono-higher fatty acid ester having 10-20 carbon atoms in the higher acyl thereof and 10-80 mols ethylene oxide per mol, about 4-10% by weight of a dimethyl higher alkyl amine oxide having 10-16 carbons in the higher alkyl thereof, about 1-7% by weight of a higher fatty acid mono- or di-ethanolamide, and about 0.05-1.0% weight of a water-soluble polyacrylamide having an average molecular weight of 100,000 to 3,000,000.
Claim 2
Dependent Claim
